Introduction to this User Manual1.

This User manual has been developed for PLC programmers who intend to connect a

Datalogic Laser Marker to a PLC via ProfiNet/IO, in order to handle the Laser Marker and

its operations following the flow of the Production Chain.

All the screenshots and tests made as a reference for the creation of this User Manual

were made using the following versions of HW and SW:

Setup over ProfiNet/IO Network2.

In order to have ProfiNet/IO connection between the PLC and the Datalogic Laser

Marker, it is necessary to set up both elements: this chapter want to show the necessary

steps and the choices which the PLC programmer can make according to his needs, in

order to have communication between these two ProfiNet/IO devices.

2.1. Configuring the Laser Marker for use over PNIO

Some operations must be made on the Laser in order to have it working on an

Profinet/IO network; PLC programmers will need to assign on each Laser Marking a

Device Name and make changes to the Firewall Rules: moreover, the User, according to

his application will have to choose the dimension of the Input and Output Memory

Areas. These changes are described in the following paragraphs.

Basic net settings of the Laser Marker

The Datalogic Laser Marking systems can be discovered on an ProfiNet/IO network only

if a number of parameters on the Laser Marker and on the PLC match. The parameters

which should match are the following:

-Device Name;

-Size of Input and Output memory maps.

The Device Name of the Laser Marker can be changed following these steps:

a) Open the ‘Laser Configuration’on the Laser Marking System, by right-clicking

the Laser Engine icon in the Windows tray bar.

b) Once the Laser Configurator is open, select the ‘Network’ voice of the menu from

the left side of the interface and the Device Name can be found under the voice

‘Device Network Name’.

Advanced net settings of the Laser Marker

All Datalogic Laser Marking devices are controlled by the Windows Firewall, which by

default settings does not allow Inbound and Outbound ProfiNet/IO traffic; in order to

establish a ProfiNet/IO connection between the PLC and the Laser Marker, the user can

either completely disable the control of the Windows Firewall, or allow all Inbound and

Outbound traffic regarding ‘LaserEngine.exe’.

To create these Inbound and outbound rules regarding the Windows Firewall, the User

can follow this procedure on the Laser Marker:

1. Enter the Control Panel and select ‘Advanced settings’.

2. New Inbound and Outbound rules need to be set for the ‘LaserEngine.exe’

program: click on ‘Inbound Rule’ and then select ‘New Rule…’.
